Mn-500 and no audio through msn messenger and webcam

I bought a logitech quickcam pro 4000 and intended to use
it. I can send and receive video, but cannot send
audio..I can hear audio. I thought it was a microphone
problem. I bypassed the router and I could send audio.
Does anyone know how to fix this?

Go to port fowarding and them to Application-Triggered
port forwardin

enable Description Outbound trigger Inbound Public type
x sound 1730 tcp 1731 tcp


Save, log off, reboot, it work for me.

Let me know if it work (E-Mail Removed)
